ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 415,236, dated November19, 1889.

Application filed April 22, 1889. Serial No. 308,078. (No model.)

To aZZ whom, it may concern:

Be it known that I, HENRY W. AVERY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Elevator-Buckets, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

My invention relates to elevator-buckets which are made of sheet metal.

It consists, primarily, of an elevator-bucket having transverse groovesformed by bending the metal substantially as shown, said groovesbeginning at a point just below the top front edge. If the grooves areformed by bending the metal inward, they may extend through a part ofthe back to near the top edge thereof. If they are bent outward, theyshould not extend into the back at all, because thereby the back of thebucket would be prevented from resting properly against the belt towhich it is attached.

The invention also consists in the combination, with said bucket, ofstraps which are secured within said grooves, and which pass through thefront wall of the bucket at points where said grooves begin, and extendabove the top edge thereof, where they are pointed to form teeth orspurs.

In the drawings, Figure l is a perspective view of an elevator-bucketembodying in the best form all the different parts of the invention, andFig. 2 is a transverse sectional view through the bucket at a pointwhere one of the grooves is formed.

Referring to the parts by letter, A represents the bucket, which may beof any suitable shape, and is preferably what is known as a seamlessbucket -that is, one formed between suitable dies from a single piece ofsheet metal.

B B represent grooves formed by bending the metal, which grooves beginnear the front top edge and run transversely partly around the bucket.These grooves strengthen the bucket and permit the use of thinnermaterial than could be employed to obtain a bucket of the same strengthwithout them. By not extending the grooves to the top of the front edgethe capacity of the bucket for gathering in the material through whichit passes is not affected by their presence. In the form shown thesegrooves are formed by pressing the metal inward, and they extend upthrough the back of the bucket to near the top edge thereof. By thisconstruction the back of the bucket lies fiat against the belt D, towhich it is properly secured, and the top edge of the bucket fitsclosely against said belt, whereby the flour or other material which isbeing elevated is prevented from getting between said bucket and belt.If the grooves were formed by pressing the metal outward, it would benecessary to obtain these results to have the grooves end before theypassed into the back. This would, however, render the bucket less strongthan it would be when constructed as shown in the drawings, andtherefore it is much the best construction to form the grooves bybending the metal inward.

As an additional feature of invention the straps O are combined withthis bucket in the manner shownthat is to say, the straps lie in thegrooves B and extend through the wall of the bucket at the point nearthe front top edge where said grooves begin, and extend upward abovesaid top edge in contact with the wall. These straps are secured to thebucket by rivets c c, and they are pointed upon their upper ends,thereby forming spurs or teeth. These spurs are of great advantage whenthe buckets are used to raise tan-bark or clay or any othertightly-packed substance, and they serve their purpose best when bentslightly forward.

I am aware that elevator-buckets have been corrugated for the purpose ofstrengthening them, and I am also aware that spurs or teeth have beenapplied to the front edge of an elevator-bucket, and I do not intend,therefore, to claim these features broadly as my invention; but

What I do claim is 1. A sheet-metal elevator-bucket having groovesformed by bending the metal, said grooves beginning just below the topfront edge and extending transversely partly around said bucket,substantially as and for the purpose specified.

2. A sheet-metal elevator-bucket having inwardly-extending grooves whichbegin near the top front edge thereof and extend transversely aroundsaid bucket and end below the top back edge thereof, substantially asand for the purpose specified.

3. A sheet-metal elevator-bucket haying grooves formed by bending themetal, said grooves beginning near the top front edge and extendingtransversely partly around said bucket, combined 'With straps which arese- IO cured Within said grooves, and which pass I through the frontWall of the bucket at the pointswhere said grooves begin and extendabove the top front edge, the extended ends of said straps beingpointed, substantially as and for the purpose specified.
